Specification of Letters Patent.

Patenten Nov. 19, 1907.

Application filed December 3l. 1903. Serial No. 187.371.

Be it k iown 'that I; ALVARO B. GRAHAM, a citizen ofthe United States,residing at Chicago, in the county of Cook and State .of Illinois, have invented certain new and Vuseful Improvements' in Paper-Feeding Machines, o f which the following is a specification.

This invention relates to a paper feeding or sheet delivery mechanism more especially intended foruse in deliverin' or feeding paper sheet by Aheet from a p1 e or stack to a 'printing press, folding machine or other appliance; and has for its objects to insure the delivery or feeding of but. one sheet of'paper at a single operation of the feeding, or delivery. devlces; to positively separate a single sheet, which is the top sheet in each instance, from als'tack or pile of paper without liability of carryingwith the top or delivered lsheet the second or following sheet on the pile` or stack; to give the feeding mechanism an action by which the rear corners ofthe top or to n i be delivered sheet willbe carried inwardly kling or inward movement of the rear corners to .release the cornefs from the remaining sheetsofthe 'pile or stack, and free the top or .to be delivered sheet for the delivery or feeding thereof to vimprove theconstruction, and operation of the devices by which "the bucof the sheet isattained; to buckle orinwardly move the rear corners of the topsheetby'the employment of suction,l 'supplied through suction cups which operate to raiseandcarry inward or u releasethe .rear corners at the proper time for the advance or delivery ofthe sheet;'to improve the construction and operation of the I retainers for holding therear corners of the sheets of the stack or pile when the top sheet is being buckled or carried inwardly at lts Arear corners; to improve the construction and operation of the forward feed devleesemploying for that purpose suction cups whlch .are advanced after the forward or leading edge ofthe sheet has been raised and held 'j by the cups to automatically throw the feedj' mascara-devi@ and appliances which en ing `mechanism out of operation .in case 'of doubling or an improper feeding of the sheet; to improve the construction and operatlon of 'the mechanism for raising the carrying table of thestack 'or pile of sheets ;y to improve `the constructionl and operation ofthe suction pump for the vacuum cup operating on the .rearand front of the sheet; and t'o improve generallythe construction and operation of ckle the corners of thesheet and ter into the m'achine or mechanism as a whole.,

The invention consists in thefeatures of construction and'combinations of parts hereinafter described and claimed.

In the drawings Figure 1 is a top or plan view of the machine or mechanism of the invention; Fig. -2- an end elevation with the lower portion of the frame broken off Fig. 3 a sectional elevation on linea a of Fig.1 looking in the directionof the arrow; Fig. '4 a top or plan view of the suction'cu'p and its operating devices or mechanismv for buck ing or moving inwardlythe rear corners of the top sheet; Fig. 5 a side elevation ofthe devices of Fig. 4, Showing the partsin their normal position; Fig. 6 a side 'elevation- `of the devices of Fig.4, showing the arts'.at the .commencement of theirinitia movement for buckling or moving inwardly the rear corner of the top sheet;,Fig. 7 a side'elevation ofthe. devices -of Fig. 4, showing v'the 'parts at the completion'A of the buckling or moving inwardly `of the'rear corners of the sheet; Fig. 8 a' top or plan view, showing a modified construction of the suction cup\and the devices for bucklingvor inwardly movinggiv the rear corners of -the sheet; Fig. 9 a side its connection to the rock. shaft by which it is raised and'lowered with the rock shaft in section; Fig; 13 a sectional elevation of the suction cu shown'in-Fig. 12, taken, on line b b'of'said gure; Fig.l 14 a sectional elevation showing a modiiication in the construction ofthe suction cups for the forward or leading edge of the sheet; Fig. 15 aside 'elevation partly in 'section of the devices for automatically throwing themachine ormechanism out of operation; Fig. 16 a detail'partlyin section. of the trip inks for releasing the clutch of the device shown in Fig. 15, taken .on line c vc of said figure; Fig. 17 a detail on line d, lshowingthe portion of the forked arm 110.v

p'lat'e ,42 and raisethe arm 41; and the arni 41' Iwill. drop to normal position lwhen the' roller 34'clears' the under face of the cani or l movement of the slide 16 which carries 4the block 33, with the limit of the rearward 'arm 32, the arnis 26 and 41 -rising and falling Jfrom their ypivotal connection to the plate 12 andthe neck or extensionl of said plate.

Theou'ter end of the arm 41 has depending therefrom 4a rod or'stein 43 on the' lower end ofwhich is a 'clamp or resser head44 which,

'when the arm 41 '.is own, presses against `the pile or -stack of paper atapoint forward ofthe rear corners, which point furnishes theA defining line for the buckling orinward movement of the corners, as shown in Figs. 4to 11 both inclusive.

The rod' 0r stem 43, in the construction' shown in Figs. 4, 5, 6 and 7, has thereon an adjustablel vcollar 45, extending laterally Vposition on the rod or stem 43.

end of the laterally extending rod or stem 46 from which is a rod or stem 46v which, as shown, is threaded at its inner end to enter a boss on 'the collar or sleeve 45 for the end of the rod or stem 46 to furnish the means of llocking thesleevepr collar 45 in its adjusted The outer has a nicked head, in the construction shown, for turning the rod or stein; and the rod or stei'ii adjacent to the head is engaged by an arm or'bar 47, the under face 48 of which is inclinedand rides on the'face of the rod or stein 46, as 'shown in Figs. 4 and 5,-for instance. The rear end of the arin or bar A47 is iXedly attached to the arm 19 carrying the suction cup,'so that with the forward movenient of the slide 16 the inclinediface 48 of the arm or bar 47 will act to .raise the cup from itsnormal position shown in Fig. 5 to its full raised position shown in Fig. 7, and

` -with the receding movement of the slide 16, 4 the arm'or bar 47 by its inclined under face 48 allows the suction cup to drop from its full raised position shown in` Fig. 7 to its nor- "mal ositioi'i shown in Figf, thus giving the -1 suction cup its rising and falling movement and its inward and out-ward travel to buckle A ,or movey inwardly the corner of the top 'sheet of aper.

, he' construction shown in Figs. 8, 9, 10

i andll differs from the construction shown in Figs. 4, 5, 6 and 7 in that the actuating arm or bar 41 for the suction cup is inclined or has a diagonal :run -instead ofbeing straight, and instead of a laterally adjustable rod or steni the bar or arm 41 .of the con-i' 'struction shown in Figs. 8 to 1 1 inclusive has bars 46 with a space between the two )lates or hars 46.in which is located a slide 47 which rides on the bars 46 and is attached to the head 20 of the suction cup. ,'.llie head 2() of the suction cup has ears 2()"-bctweeu which is pivoted by a suitable pin or pivot ".10", the t o\\'nwardly turned end of au arui 19 eorrespr-inding to the arm 19 and pivoted' between ears 17 on the slide 16. '.l ie bars 46a have an upward inclina-tion, when theI presser head 44 is resting on the stack ol' paper as shown in Fig. S), aiid'with the forward movement of the'slide .16, the slide 47 moves outwardly on the guide bars 46, and suchoutward movexient, owing to the upward inclination of ythe side bars, acts to raise the suction cup 22 with the sheet ol' paper caught and he d against its. acting 1end tace, and to buckle or move inward the corner of the sheet, as shown in Fig. 1l), such movement continuing until the barsii-ssume the position shown in Fie'. 11, at which time the corner of the sheet is released from the suction cup and the rear edge of the sheet is free of the stack of sheets so that the upper sheet can be fed forward b v the frontfeeding devices. The arm 41 with its presser hea-d 44 is raised by contact with the end of the arm 32, as the roller 34 passes under the cam block 33, freeing the upper sheet of paper from the presser head 44 to -bc fed forward by the front feeding mechanism.

- A stud or pin 49 extends up from the plate 12 and has mounted thereon a socket or bearing 50, extending laterally from which on one vside isan ar'm 51'having in its 'outer end a slot 52 into which is entered a pin 53 upwardly projecting from the slide 16, and by whie i arm with its slot and the pin, the slide is reciprocated, the return movement of the slide being limited, as shown, by a 'stop pin 12a on the plate 12 at the'outer or rear end of the slideway. An arni54 extends ylaterally from the side of the socket or beaiing 50 and its outer end has an upwardly extending in 55 which receives a block vor yhead 56 iaving onl one side ears 57 between which is located ablock 58, and on the block or head 56 and one of the ears 57 are ears 59,

"between which is ivoted one end of a finger piece or lever 60, iaving a dependinu' wedge 61 which enters the spaces between tlie head or block 56 and the 'block 58 and furnishes the means for moving the block 58 outwardly,

- so that the blocks 56 land 58 in connection with the iinger'piece or lever and its' wedge form a clamp.

A rod 62 at its rear end passes through the ears 57 and the block '58 so that when the block is forced outward by the depression of the .finger piecev or lever 60 through the action of the Wedge 61, theend' of the rod will and ears connecting the rod 62 with the slide 16 through the pivoted or rocking arms 51 be tightly clamped and held by the block 55' andextending from outer end of Which-hasjonrnaled thereon by' which roller .and i 54,5'jby which. thel reciprocating move, ments. theelflw'illbe' given from the reoiprocation 'ofthe rod-@forward and haek- Ward-' The forwaid end o'ltheod' 62 .ie-'Se- -5' ol'ued 'in ahoga S51-Eon ag, Socket or sleeve" '63,

The outer end ofthe link 105 is pivotally connected to a4 bracket 106 havingan ear through which passes an adjusting screw 10T by means of which the links are held from dropping down below a straightline, as -shown in Fig. 15. 'lhe'lree end of the link 10Jl is pivotally attached to a lever 10S, which lever has a lateral ear 109, pivotally connected to an ear or bracket 110 so that the lever can be oseillated or vibrated toi ward and from the end of 'the frame; the upperend of the lever'has projecting out therefrom a pin 111 encircled by a coiled spring, one end ofthe spring bearing againsty the face of the lever and the other end against the face ofthe upright SS, b v means of which .spring the lever is returned to normal position. 'lhe upper end of the lever has a. fork or siirrup 113 whit-lr is entered into a eirculnferenal grtiove 11-1 in the head 115 caluving `the arln Si). so that with the outward throw of the forked end of the lever 10S, the head will be moved or slide outward on the end-of the shaft 36, disengaging the connection of the arm S9 with the shaft. The head 115, in the arrangement shown, is engaged with the shaff: byholes 116 in itsinner face which engage pins 117 on a collar 11S locked to the shaft S6 by a set bolt 119 or otherwise, so that when the parts are normal and the pins 117 are engaged with the holes 116, the shaft S6 will be rocked from the vibration of the arm or lever 89 and cause the arm 84 to advance and recede the rock shaft 64 to give the required throw for opert ating the front suction cups and the devices bv which the corner suction cups for the rear of the sheet are operated. TheV disengagement of the head 115 from the collar 118 allows l the arm or lever to vibrate without rocking the shaft 86, and, as shown, the sliding head 115 `is held in proper relation'on the end of the shaft 86 by a tongue 120 entering a roove 121l in the shaft, as shown in Fig. 21`, or the tongue and groove to be disengaged when thehead is moved back and to be engaged-when the head is moved forward. j

" An arm 122 is attached at its upper end `to the shaft 64 -and its lower end isI connected by' a pivoted link 123 with the end of an arm 124 having a sleeve 125 .mountedon a j ournal f pin 126 extending out. from the end frame and the sleeve 125 has extendingout therefrom anari1i"127, the outer end of to the end frame of the machine.

4ing of two sections, one section leading to the head ofone suction cup and the other-section connecting the heads of the two suction cups, as shown in Fig. 1. The lower end of the suction pump 130 has a nipple 133 connected with which is a pipe 134, extending laterally and upwardly and having at its upper end a nipple 135 connected with which is the end of a hose 136, the hose leading to and having connection with the heads 67 through the nipples 63 for the front suction cups yand, as shown in F ig. 1, the hose 136 leads to the head of the end suction cup, and sections of hose 136n connect the heads of the other suction cups, but the hose 136, with the construction of ht d shown in Fig. 1-1, would be connected with the center suction cup and that suction cup would he connected b v hose sections 1361 with the end cups. 'lhe cylinder 03 at its closed end, has a nipple 137 leading from which is a hose 13S connected with the end of a vertical pipe 1230, the upper end ol' which terminates helow the plane ol travel of the front suction cups; and, as shown, the pipe 130 is held by a bracket 1-.10 attached to a. cross piece 141 on the frame. This pipe, with its open end below the plane of travel of the top or delivered sheet, furnishes a means for automatically stopping the mechanism is ease of a failure of the suction cups at the front side of the machine to engage and carry forward the top sheet, as with the release of a top sheet suoli sheet would drop over the open end of the tube 139 and shut off the inflow of air through the tube 'to the cylinder 9S,

and with the. stoppage of such -inilow a vacuum would be created in front of the piston of the cylinder 9S by which the pressure on the piston at the open end of the cylinder .would move the piston inward and, through the piston rod 99 and arms 100 and 103, trip the links 104 and 105 for the spring 112 to act and throw the upper end ofthe lever 10S outward, disengaging the head 115 from the collar 113 and stopping the.rocking of the shaft S6 and the parts actuated therefrom.

The rock shaft S6 has -ixedly secured thereto an arni 142 to the upper end of which is pivoteda linker bar143, having its outer end pivotally connected with a slide 144, movable on a standard or lever 146 and adjustable thereon to diiierent lengths, and when adjusted, locked thereto by a set'bolt 145, so thaty the throw of the arm 142 forwere mi fbaekwtfd et" te est?, from ing.Meneer.@meister limite', which' lL- tghgzlioqjk of the 'Shaft-,Srylfgiyeth-stsndf.- is Igiven -arfalliiig.end rising `moyerrient from'.
